Abstract (en)
[origin: WO2021207149A1] Disclosed herein is a multi-purpose aerosol platform capable of producing and delivery of submicron and nano structured materials for pharmaceutical, biomedical and environmental applications. Depending on the application, active chemical and biological materials may be processed from liquid dispersions into droplets and/or particle formulations. The disclosed system uses moderate gas pressures to atomize liquids into submicron-size droplets that are 10-1000 times smaller in diameter than commercial and research systems. This allows much gentler and rapid droplet-to-particle conversion, applying much smaller physical and chemical stresses on the processed materials than conventional techniques like spray drying, spray coating, spray freeze drying and other technologies. For example, the disclosed system can be used for an ultra-fine nebulization and delivery of viscous therapeutic oils including oils of medical cannabis, for which conventional nebulization systems either fail or became ineffective. Such systems could help patients with acute respiratory distress syndrome (ARDS) developed in hard COVID-19 cases.
